Decision Infrastructure and Harvey

How Decision Infrastructure complements legal AI and reasoning tools in the legal technology stack.

Why this is not a replacement relationship

Harvey is a powerful legal AI platform for reasoning, research, analysis, and drafting. Decision Infrastructure does not replace it — it adds the runtime layer that governs whether the consequential actions taken from that reasoning remain admissible at the moment they execute.

They sit at different layers of the same stack: Harvey operates at the legal research and analysis layer; Decision Infrastructure operates at L6 — the governance layer between decisions and their consequences.

What Harvey Does Well

Harvey is a broad legal AI and reasoning platform. Within a legal team it can:

  • generate legal research and analysis across large corpora
  • draft documents, memos, and contract language
  • answer complex legal questions with cited reasoning
  • accelerate review, due diligence, and summarization
  • support legal reasoning and workflows end to end

What Happens After Harvey?

Harvey produces legal reasoning, analysis, and drafts. Decision Infrastructure validates admissibility before the consequential actions taken from that reasoning become real.

Examples include:

  • due diligence findings
  • deal-risk recommendations
  • draft contract language
  • regulatory assessments
  • litigation strategy analysis

The question shifts from “what does the analysis recommend?” to “may the resulting action execute now?” — and that question is resolved at L6. The same shift applies across due diligence, fundraising, M&A, regulatory review, and litigation analysis.

Decision Infrastructure governs whether those actions may execute now.

What Decision Systems Fix — and What They Don’t

L5 · Decision Systems

Decision Systems

What they fix

  • Structured decisions
  • Decision tracking
  • Traceability
  • Repeatability

What they don’t answer

  • Should this decision exist?
  • Is it valid under current constraints?
  • Can it control execution?
  • Will it produce evidence?

Core question: “What decision was made?”

L6 · Decision Infrastructure

Decision Infrastructure

What it adds

  • Decisions validated before execution
  • Policy enforced at runtime
  • Human and AI accountability
  • Evidence across the lifecycle
  • Runtime admissibility

Core shift

From structuring decisions to governing whether decisions are valid, executable, and accountable.

Core question: “Is this decision valid, executable, and defensible?”

Most platforms optimize decisions. Very few govern them.

L5, L6, and L7: Different Roles

Harvey informs the decision; Decision Infrastructure governs the act. The distinction is not a feature gap — it is a different layer of the stack.

L5 produces and routes decisions.

L6 governs whether those decisions remain admissible at execution.

L7 learns from the outcomes of governed execution.

Why Trusted Decision Intelligence Requires L6

Decision Systems determine what should happen. Decision Infrastructure determines whether it may happen now.

Decision Intelligence learns from outcomes. If those outcomes were never validated at execution, the learning is built on actions that may never have been admissible.

Decision Intelligence is not the input to Decision Infrastructure. It is the output of governed execution.

Frequently Asked Questions

Is Decision Infrastructure a legal AI system?

No. It is not a legal AI or reasoning tool. Tools like Harvey generate legal reasoning, analysis, and drafts; Decision Infrastructure is the runtime governance layer (L6) that determines whether the consequential actions taken from that reasoning remain admissible at execution. They are complementary layers.

Does it replace legal reasoning?

No. Harvey produces the reasoning, analysis, and drafting; Decision Infrastructure governs whether the actions taken from that reasoning may execute now — admissible, authorized, compliant, and evidenced at the moment they occur. It governs the act, not the analysis.

What happens after AI-assisted legal analysis?

The analysis becomes the basis for a consequential action. Decision Infrastructure revalidates, at the commit boundary, whether that action is still admissible under current authority, policy, and constraints — and returns Allow, Hold, Deny, or Escalate with evidence before it executes.

Is it a Harvey replacement?

No. It does not generate legal reasoning, research, or drafts. It governs the admissibility of actions at the commit boundary — independent of, and portable across, the systems that produce those actions, including Harvey.

Can it run alongside Harvey?

Yes. Harvey produces the legal reasoning and drafts; Decision Infrastructure governs whether each resulting action is admissible at execution and captures independent evidence. The reasoning layer produces; L6 governs the act.

Why does Decision Intelligence depend on L6?

Decision Intelligence (L7) learns from outcomes. Without L6, it may learn from legal actions that were never admissible. With L6, it learns only from governed execution — making the resulting intelligence trustworthy.
